CPANSA-Mojolicious-2022-03 (2022-12-10)

Mojo::DOM did not correctly parse <script> tags.

CPANSA-Mojolicious-2021-02 (2021-06-01)

Small sessions could be used as part of a brute-force attack to decode the session secret.

CVE-2021-47208 (2021-03-16)

A bug in format detection can potentially be exploited for a DoS attack.

CVE-2018-25100 (2018-02-13)

Mojo::UserAgent::CookieJar leaks old cookies because of the missing host_only flag on empty domain.

CPANSA-Mojolicious-2018-03 (2018-05-19)

Mojo::UserAgent was not checking peer SSL certificates by default.

CVE-2020-36829 (2020-11-10)

Mojo::Util secure_compare can leak the string length. By immediately returning when the two strings are not the same length, the function allows an attacker to guess the length of the secret string using timing attacks.

CPANSA-Mojolicious-2018-02 (2018-05-11)

GET requests with embedded backslashes can be used to access local files on Windows hosts

CVE-2024-58134 (2025-05-03)

Mojolicious versions from 0.999922 for Perl uses a hard coded string, or the application's class name, as a HMAC session secret by default. These predictable default secrets can be exploited to forge session cookies. An attacker who knows or guesses the secret could compute valid HMAC signatures for the session cookie, allowing them to tamper with or hijack another user's session.

NAME

Mojo::IOLoop::Stream - Non-blocking I/O stream

SYNOPSIS

use Mojo::IOLoop::Stream;

# Create stream
my $stream = Mojo::IOLoop::Stream->new($handle);
$stream->on(read => sub {
  my ($stream, $bytes) = @_;
  ...
});
$stream->on(close => sub {
  my $stream = shift;
  ...
});
$stream->on(error => sub {
  my ($stream, $err) = @_;
  ...
});

# Start and stop watching for new data
$stream->start;
$stream->stop;

# Start reactor if necessary
$stream->reactor->start unless $stream->reactor->is_running;

DESCRIPTION

Mojo::IOLoop::Stream is a container for I/O streams used by Mojo::IOLoop.

EVENTS

Mojo::IOLoop::Stream inherits all events from Mojo::EventEmitter and can emit the following new ones.

close

$stream->on(close => sub {
  my $stream = shift;
  ...
});

Emitted if the stream gets closed.

drain

$stream->on(drain => sub {
  my $stream = shift;
  ...
});

Emitted once all data has been written.

error

$stream->on(error => sub {
  my ($stream, $err) = @_;
  ...
});

Emitted if an error occurs on the stream, fatal if unhandled.

read

$stream->on(read => sub {
  my ($stream, $bytes) = @_;
  ...
});

Emitted if new data arrives on the stream.

timeout

$stream->on(timeout => sub {
  my $stream = shift;
  ...
});

Emitted if the stream has been inactive for too long and will get closed automatically.

write

$stream->on(write => sub {
  my ($stream, $bytes) = @_;
  ...
});

Emitted if new data has been written to the stream.

ATTRIBUTES

Mojo::IOLoop::Stream implements the following attributes.

reactor

my $reactor = $stream->reactor;
$stream     = $stream->reactor(Mojo::Reactor::Poll->new);

Low-level event reactor, defaults to the reactor attribute value of the global Mojo::IOLoop singleton.

METHODS

Mojo::IOLoop::Stream inherits all methods from Mojo::EventEmitter and implements the following new ones.

close

$stream->close;

Close stream immediately.

close_gracefully

$stream->close_gracefully;

Close stream gracefully.

handle

my $handle = $stream->handle;

Get handle for stream, usually an IO::Socket::IP or IO::Socket::SSL object.

is_readable

my $bool = $stream->is_readable;

Quick non-blocking check if stream is readable, useful for identifying tainted sockets.

is_writing

my $bool = $stream->is_writing;

Check if stream is writing.

new

my $stream = Mojo::IOLoop::Stream->new($handle);

Construct a new Mojo::IOLoop::Stream object.

start

$stream->start;

Start or resume watching for new data on the stream.

steal_handle

my $handle = $stream->steal_handle;

Steal "handle" and prevent it from getting closed automatically.

stop

$stream->stop;

Stop watching for new data on the stream.

timeout

my $timeout = $stream->timeout;
$stream     = $stream->timeout(45);

Maximum amount of time in seconds stream can be inactive before getting closed automatically, defaults to 15. Setting the value to 0 will allow this stream to be inactive indefinitely.

write

$stream = $stream->write($bytes);
$stream = $stream->write($bytes => sub {...});

Write data to stream, the optional drain callback will be executed once all data has been written.
